A project underway at The University of New Mexico(UNM) is aimed at demonstrating that semiconductor laser devices can send data at a bandwidth speed of over 100 Gbits/s, with potential applications that could result in ten times the speed of current fibre optic networks.

The project addresses the need for faster data transfer by increasing the speed at which signals are first generated to send through at fibre optic network. For the past two and half years, work has centred on numerical simulations of proposed devices. The laboratory work will be performed ar UNM's Center for High Technology Materials(CHTM).

In a posting on the UNM Newsroom website, author Sharon Steely quotes Prof. Osinski:" Development of inexpensive ultrafast chips operating at speeds exceeding 100 Gbits/s will have a huge societal impact by increasing the transmission capacity of fibre-based networks."

Osinski's project explores the use of semiconductor ring lasers to provide energy-efficient high-speed optical data egress(exit) from a cryogenic environment to room temperature for further processing.

" Ultra-high-speed (>100 GHz) on-chip modulation of integrated lasers is an important 'holy grail' for the ever-increasing demand for ultrafast communication."
